SHOCKING INTERNET CONNECTION AND SERVICE

If I could give this business a zero rating then I would. I messaged them 3 weeks ago with the issue that our internet at home is completely shocking, we cannot watch a full movie on Netflix without it lagging, the modem only picks up signal outside on the balcony so basically when its rain we are completely *****ed and cant use the wifi, not a single word back from them. I have purchased so much data this month, I cant go without internet as my bookings and appointments for work are all done online. Ive spent more money this month on data for my phone than for the internet. Rain must try and deduct money next month, Ill go straight to the ombudsman.
